Sampling & confidence intervals
Answer engines are non-deterministic: ask the same question twice and you can get different answers, different citations, a different brand. Reporting a single run as a probability would be dishonest. Instead Lokrix treats non-determinism as a first-class concept and measures it directly.
Monte-Carlo sampling
For each prompt, Lokrix runs the engine K times across varied temperature, persona and locale. Each run is scored for presence — was your brand surfaced (cited, linked, recommended or named)? The fraction of runs where it was surfaced is the Monte-Carlo presence probability.
Confidence intervals
A probability from a finite sample carries uncertainty, so Lokrix reports a 95% confidence interval around every presence estimate. More samples narrow the interval; fewer samples widen it. This is why you see a range, not a single number — a presence of 60% with a wide interval means something very different from 60% measured tightly.
The same interval propagates into the composite Lokrix AI Score, which is always reported with its own 95% CI.
Context is always disclosed
Because the persona, locale and time window shape the result, they are disclosed alongside every measurement. A presence probability is only meaningful with its context, and Lokrix never hides it. More samples cost more credits, so K is a deliberate trade-off between tighter intervals and run cost.
